浅灰线框手锯3D模型

纯白背景居中的单视角3D建模渲染图，一把经典手锯/钢锯水平放置，整体为浅灰色单色实体与线框混合质感，表面覆盖细密三角和四边形网格线；左侧为圆柱形握柄与连接座，下方为细长锯片，右侧为带蝶形螺母的张紧装置，上方为弧形锯架，锯架顶部有矩形加固片及若干铆钉和孔位；正交侧视构图，完整展示工具轮廓，无人物，无文字，背景纯白，均匀柔光，画幅约10:3。

Centered single-view 3D modeling render on a pure white background of a classic hacksaw laid horizontally, monochrome light gray solid-and-wireframe style covered with a fine mesh grid; cylindrical handle and mounting bracket on the left, a long thin saw blade along the bottom, a wingnut tensioner on the right, and an arched top frame with a rectangular reinforcement plate and visible rivets and holes; orthographic side-view composition showing the complete tool silhouette, no people, no text, pure white background, even soft lighting, aspect ratio about 10:3.
